Conductive cement-based composites with nano-graphite, carbon black have good conductivity and piezoresistive properties, and it can use to achieve traffic monitoring. In this paper, the piezoresistive properties of high conductivity cuboid cement-based composites with any two-phase composed of graphite, carbon black, carbon fiber, under the standard vehicle force with different load cycle are studied. For the selected cases, experimental results show that cement-based composite mixed with graphite and carbon fiber under a certain ratio and vehicle force has the best piezoresistive properties, and compound conductive phase mixed with graphite and carbon black is better than that mixed with carbon black and carbon fiber.
